Ages ago I deployed a sophos virtual appliance in AWS, so I could centrally enforce some basic firewall rules, in a way that my management could understand. There was only 1 server behind it, the same thing could have been achieved simply using the standard built in security rules. I think about it often. I do find Azures implementation of this stuff pretty baffling. Just in, networking concepts being digested by software engineers, and then regurgitated into a hierarchy that makes sense to them. Not impermeable, just weird.
